What does this NCERT chapter cover?

1. Understanding length using non-standard units like hand spans and footsteps  
2. Comparing lengths using strings, ropes, and visual observation  
3. Learning standard measurement using metre rope and measuring tape  
4. Classifying objects based on their size and length  
5. Activity-based learning like drawing, measuring, jumping, and throwing  

How to use these NCERT solutions?

1. First read and attempt each question from the worksheet carefully.
2. Use the answers to check your work after attempting independently.
3. Follow the same order as given in the worksheet for better understanding.
4. Parents and teachers should guide students during activity-based tasks.
5. Use real-life objects to practice measurement concepts.

Important tips & tricks for students

1. Always observe pictures carefully before answering questions.
2. Use the same measuring unit when comparing objects.
3. Remember non-standard units may give different results for different people.
4. Practice measuring using ropes, steps, or simple tools at home.

NCERT solutions – complete answer key

Let us Do

1. Decorating the classroom with paper strings. 
Measuring a table using hand spans. 
Measuring the height of a door using a string. 
Decorating the board. 
Measuring distances using footsteps or strings, etc. 

2. Shelly measures the height of the door using a string and then compares its length. 

3. No,  
They will not get the same measurement because hand spans differ from person to person, so the measurement will vary. 

4. The girl standing near the door (right side) has the longest ponytail. 

5. The vertical paper strings hanging beside the window are equal to the height of the window. 

6. Footsteps, hand spans, a long paper string or a rope, and measuring tape. (Best method)  
A measuring tape is more accurate because it gives the same result for everyone, unlike footsteps or hand spans. 

7. Ways used to measure length: hand span, footsteps, and paper strings. 
Measuring with a rope or measuring tape is better because it gives accurate and standard measurements that are the same for everyone, unlike hand spans or footsteps. 

Let us Do

Paper Strings Activity

1. (a) Shortest string – red (b) Longest string – green  

2. By counting remaining gaps in the border, 2 more paper strings are needed.

3. Total number counted from the picture = 8 paper strings. 

Let us Do

Drawing and Thread Activities

1. Thread of equal length pasted  

2. A longer string is drawn. 

3. A shorter string is drawn.

4. The other half of the moustache is drawn symmetrically.

5. The longest string is identified by counting the number of bulbs attached. The string with the highest number of bulbs is the longest. We can also compare lengths directly. 

Are these true for all?

These are not true for all children because body measurements differ for each person. 

1. Your head is 3 handspans round — False  

2. The length of your forearm is equal to the length of your feet — False  

3. Your height is equal to the length of your arms wide open — True  

Table and Door Measurement

Measure the length and breadth of the table using a rope or string and compare it with the width of the door. 
Even if both length and breadth are more than the width of the door, the table can still pass by tilting or turning it diagonally. 

Let us play.

Arrange boxes or bags to form a bridge. Place objects under the bridge and check whether they pass through or not. Guess and test different objects. 

Large objects such as big tables, cupboards, buses, and trucks cannot pass through the school gate because their size is larger than the gate. 

Steps for Making a Metre Long Rope

Use a metre rod or tape to measure one metre on a rope. 
Mark the length and tie knots to indicate one metre. 

Height Measurement Activity

Heights more than one metre  
Riya  
Meera  
Arjun  
Neha  

Heights less than one metre  
Ritu  
Anu  
Kabir  
Rohan  

The tallest child  

Boy standing on ground (right side) (as per image comparison)  
The girl standing on the box only appears taller because she is standing on a raised surface. 

Objects Around You

Answers may vary based on objects available around. 
Larger objects → more than 1 metre  
Smaller objects → less than 1 metre  
Exact measurement → equal to 1 metre  

Let us Do

Objects are placed in categories by comparing their size with quarter-metre, half-metre, and one-metre references. 

Jump Activity

Children are categorized based on jump distance (more than 1 m, 1/2 m, 1/4 m). Measured using metre rope  
Answers may vary.  

Throwing Activity

The distance of the throw can be measured using a metre rope, for example 2 metres or 3 metres depending on how far the object is thrown. 

Let us Do

1. Height measured using metre rope. 

2. The student whose estimated length is closest to one metre when measured using the metre rope is correct. 

3. To make 4 equal pieces, 3 cuts are required.

4. About 2 to 4 footsteps fit into one metre, depending on the size of a person’s steps. 

5. Wall length measured using repeated placement of metre rope
